The work is dedicated to:

This project is aimed at developing a seismic platform for investigating seismic resistance of buildings and structures.

Objects of research:

High-rise buildings and structures, hydroelectric dams, nuclear power plants, chemical industry enterprises.

Goal:

This work is the development and implementation of technology to regulate and manage the hydro system of the seismic platform.

The main task:

The calculation of seismic resistance of models of industrial and civil facilities and practical testing as well as the training of specialists and specialists in this field is considered.

In areas with high seismic activity, destructive earthquakes of intensity seven or more points are possible at any time. Therefore, for the safety of people, it is necessary to build sound buildings capable of resisting seismic influences. Therefore, at the design stage of the objects, seismic loads, which are determined depending on the seismicity of the area, must be taken into account for buildings and structures.

The technology of simulating seismic loading is based on the use of hydraulic drives and a vibrator. As a criterion for the adequacy of the reproduction of the seismic action, the specified amplitude values ​​of the motion parameters (accelerations, velocities, displacements) of the seismic platform were taken into account, as well as the completeness of the envelope of the calculated reaction spectra.

The stability of the structure will be tested for seismic stability of the structure under conditions of repeated dynamic loading adequate to the seismic effect of earthquakes of intensity up to 9-11 points on the MSK-64 scale inclusive.

Joint-stock company “Uzavtosanoat” is interested in developing a three-coordinate seismic platform for testing objects, fragments and models of buildings and structures for seismic resistance. The conducted tender studies revealed that similar seismic platforms of foreign production are sold at inflated prices. Therefore, the protocol of the meeting of the Board of Trustees of the Turin Polytechnic University in Tashkent decided to develop and implement the seismic platform on its own at the Mechatronics center of the Turin Polytechnic University in Tashkent.

The main objective of this project is not only practical testing and calculation of models of industrial and civil facilities, but also training of specialists and specialists in this field.
